This calculator is intended solely for general information and educational purposes. You should not take any action on the basis of the information provided through this calculator. ## How can I calculate a percentage change ?

To calculate a percentage change, you can use this formula: (((y2- y1))/ y1) * 100. So, let's break this down with an example:

Suppose George owns stock in Vandelay Industries. His stock price went from $45 per share, to$47 per share. By what percentage has George's stock inceased ?

• We can set y1 = 45, and y2 = 47 (y1 is your first value, y2 is the value it changed to)
• Now subtract y2 - y1, which in our case is 47 - 45 which is 2
• Now divide 2 by 45 which is .044
• Multiply .04 * 100 which gives you 4.4

So George's stock has increased by 4.44 percent. • Compound Interest

## Understanding percentage change

How to calculate percent change, percentage discount example, percentage increase example.

Let's begin by discussing what percentage change is, and we can then go through how to calculate it, with some examples to help.

Percentage change is a fundamental mathematical concept that allows us to measure and compare the relative difference between two values. Performing this calculation can help us see how much something has increased or decreased in value or quantity over time.

You'll find percentage change figures widely referenced in fields such as finance, economics and statistics. For example, you may find yourself looking at a statement for an investment and wondering what the percentage increase (in interest) has been compared to your initial investment.

You'll also find occasions in everyday life where calculating percentage change is useful. For example, there may be a sale at your local electrical store, and you might find yourself wanting to compare the price of an item before and after a discount, to evaluate the discount.

To calculate percentage change, subtract your initial value from your final value to get the difference, and then divide that figure by the initial value. Multiply the result by 100 to get the percentage: (finalValue − initialValue) / initialValue × 100 .

Here's the step-by-step process for calculating percentage change:

• Determine the initial value (old value) and the final value (new value).
• Subtract the initial value from the final value: final value - initial value .
• Divide the resulting figure by the initial value .
• Multiply the result by 100 to convert to a percentage .

The result from above represents the percentage change between the initial value and the final value. If the result is positive, it indicates an increase, while a negative result signifies a decrease.

Let's have a look at this as a formula...

Using this formula, when numbers go up, you can work out the percentage increase . When numbers go down, you can work out the percentage decrease . You need to make sure you do the calculation in the correct order, using PEMDAS . So, numbers within brackets first.

Example scenario 1 : You are shopping for a new laptop, and you come across a model that initially costs $1,000. However, you notice that it is on sale at a discounted price. You want to calculate the percentage change in price. First, let's get our values: • Initial price :$1,000 (old value).
• Discounted price : $800 (new value). Now, we can calculate the percentage change: • Subtract the initial price from the discounted price:$800 - $1,000 = -$200.
• Divide the result by the initial price: -$200 /$1,000 = -0.2.
• Multiply the resulting figure by 100 to convert it into a percentage: -0.2 * 100 = -20%.

The calculated percentage change is -20%, indicating a 20% discount on the original price.

Example scenario 2 : You find out that your landlord is increasing your rent from $650 to$700 per month and you want to know what the percentage increase is. Let's work it out...

• New number - old number = increase

## X Percent of Y Formula

x% of y is y * (x / 100)

In the example above that would be calculated as 500 * (20 / 100) = 500 * 0.2 = 100. If you were to purchase the $500 item with$20 off, you would be getting a discount of $100. Another example of using a percent calculator would be if you wonder how many minutes are 75% of a 60-minute video. The answer is 60 * (75 / 100) = 45 minutes as you can verify with our tool. ## How to calculate percent difference The percentage difference of two numbers (quantities) a and b is the relative difference, expressed as a percent. It should be calculated using the formula: ## Percentage Difference Formula Percent Difference = |a - b| / ((a + b) / 2) * 100 percent For example, if one item costs$5 and another costs $6 the percent difference between them is: |5 - 6| / ((5 + 6) / 2) * 100 = 1 / (11 / 2) * 100 = 1 / 5.5 * 100 = 18.18%. Please, note that this doesn't mean that 5 is 18.18% smaller than 6, or that 6 is 18.18% larger than 5. The correct percentages if you are asking the question of "what percent is a from b" would be 16.66% and 20%, respectively, as explained above. Similarly, a percentage difference calculator might be useful if computing the difference in elevation of two mountains. If one is 6,000 feet high and the other 3,000 feet, the absolute difference is 2000 ft while the percent difference is 40%. Percentage difference is useful in a few situations, so it should be used with care. For example, one should not use percentage difference when comparing time periods, as the first metric is another state of the second metric, so percent change is the appropriate calculation. Similarly, finding a price changed by some percentage should not be done using percentage difference. ## Percent Points vs Relative Percentages You might have noted that often when newspapers are talking about USA elections for members of parliament, premier, or president of a town, municipality, or a whole country, there would be polls tracking the favorability of each candidate. Differences in sentiment and changes in said polling measures will often be communicated in percent points instead of percentages. A percent point is like absolute difference, but expressed in percentages. Note that such calculations only apply when comparing differences in percentage measures - something not supported by our percentage difference calculator mode. For example, the percent in favor of candidate A might be 40% before a certain political event and only 35% after. The percent change is simply 40% minus 35% which equals 5 p.p. (but is a percentage change of 12.5 percent). ## Compounding and averaging percentages Percentages should not be added up (compounded) or averaged like simple numbers, as this will result in an incorrect end result. Compounding is often encountered in finance, e.g. when calculating compound interest or multi-year return of a financial portfolio. Averaging percentages is often encountered in business calculations, for example to determine the average growth of a company, but also in finance and banking where average growth of an asset or asset portfolio may be calculated. Here is an example of adding percentages : say you have a$100,000 bank deposit at a 2% interest rate, applied yearly at the end of the year. If you keep it for 5 years, you might think that the way to calculate your deposit's value at the end of the 5-year period is to simply multiply 2% x 5 = 10% (or, equivalently, 2% + 2% + 2% + 2% + 2% = 10%), add 100% and then use our percentage calculator to calculate 110% of $100,000. By this calculation you would expect to have$110,000 at the end of the period (10% of 100,000 is $10,000). However, you will have$110,408, since at the end of each year you will get your interest but then in each of the following years you will accrue interest over the interest from the first year. And so on for the second, third...

To average percentage growth a year, it would be incorrect to just sum up the growth % in each year and then divide by the number of years. Let us say you are the founder of an organization which has an asset that grew 5% the first year, 6% the second year, 10% the third year, and then lost 10% the fourth year. The growth of the principal value is not 5% + 6% + 10% - 10% = 11%, but it is instead the geometric mean : 2.4549% times the number of years = 2.4549 x 4 = 9.82%. Again, this is not something you can solve for using the above calculator.

The above peculiarities are also the reason why if you lose 25% of some asset, you need to grow it 33.33% to recoup the loss. A quick calculation shows that $10,000 * 25% =$7,500, while $10,000 of$7,500 = 133.33% (or $10,000 -$7,500 = $2,500 to return to zero, and$2.500 is 33.33% of $7,500). ## Many uses for a percentage calculator As the numerous examples above demonstrate, a percentage calculator can be useful in so many practical scenarios. Changes in electoral sentiment in democratic processes, industrial production, stocks of material goods in warehouses, albums sold by an artist / musician, publications in a scientific journal, personnel changes in an organization, as well as natural things such as the amount of flora or fauna in given island, etc. can be computed using such a tool. Another application of percentage calculations is for differences in achievements such as records at Olympic games and other tournaments and championships. A specialized calculator can be used to measure the relative difference in physical quantities such as speed, density, luminosity, reflectivity, strength, tensile strength, and so on. However, a calculator is most often used for financial assets and benchmarks and for everyday things such as discounts, commissions, and tipping at a restaurant. ## Cite this calculator & page If you'd like to cite this online calculator resource and information as provided on the page, you can use the following citation: Georgiev G.Z., "Percentage Calculator" , [online] Available at: https://www.gigacalculator.com/calculators/percentage-calculator.php URL [Accessed Date: 15 Nov, 2023]. ## Math calculators • PRO Courses Guides New Tech Help Pro Expert Videos About wikiHow Pro Upgrade Sign In • EDIT Edit this Article • EXPLORE Tech Help Pro About Us Random Article Quizzes Request a New Article Community Dashboard This Or That Game Popular Categories Arts and Entertainment Artwork Books Movies Computers and Electronics Computers Phone Skills Technology Hacks Health Men's Health Mental Health Women's Health Relationships Dating Love Relationship Issues Hobbies and Crafts Crafts Drawing Games Education & Communication Communication Skills Personal Development Studying Personal Care and Style Fashion Hair Care Personal Hygiene Youth Personal Care School Stuff Dating All Categories Arts and Entertainment Finance and Business Home and Garden Relationship Quizzes Cars & Other Vehicles Food and Entertaining Personal Care and Style Sports and Fitness Computers and Electronics Health Pets and Animals Travel Education & Communication Hobbies and Crafts Philosophy and Religion Work World Family Life Holidays and Traditions Relationships Youth • Browse Articles • Learn Something New • Quizzes Hot • This Or That Game New • Train Your Brain • Explore More • Support wikiHow • About wikiHow • Log in / Sign up • Education and Communications • Mathematics ## How to Calculate Percent Change Last Updated: January 31, 2023 Fact Checked This article was co-authored by Grace Imson, MA and by wikiHow staff writer, Sophia Latorre .

In mathematics, the concept of percent change is used to describe the relationship between an old value and new value. Specifically, the percent change expresses the difference between the old and new values as a percentage of the old value. Use the equation (( V 2 - V 1 ) / V 1 ) × 100 , in which V 1 represents an old or initial value and V 2 represents the new or current value. If the number is positive, it indicates a percent increase and if it’s negative, it indicates a percent decrease. You can also use a modified formula to determine percent decrease rather than working with negative numbers. ## Sample Percent Change Calculator ## Using the Standard Equation • For example, say you’re trying to figure out how much your income increased from one year to the next. If you made$37,000 last year and $45,000 this year, subtract 37,000 from 45,000, which is 8,000. • Alternatively, in the world of retail, when a product receives a discount, this is often expressed as the product being “x% off” which is a percent decrease. If a pair of pants was previously sold for$50 and is now sold for $30,$50 is the original value and $30 is the new value. To start, subtract$50 from $30, which is -$20.

Tip: When dealing with variables with more than one change in value, find the percent change only for the two values you wish to compare. • Continuing the example, divide 8,000 (the difference between your incomes) by 37,000 (which is the original value). The answer is 0.216.
• Alternatively, dividing the difference (-$20) by the old value ($50) is -0.40. Another way of thinking of this is that the $20 change in value is 0.40 of the$50 starting point, and that the change of value was in the negative direction. • Take 0.216 and multiply it by 100. In this case, the answer is 21.6, so your income increased by 21.6%.
• Alternatively, to get the final percentage, multiply the decimal answer (-0.40) by 100. -0.40 × 100 = -40%. This means that the new price of $30 for the pants is 40% less than the old price of$50. In other words, the pants are 40% off. Another way to think of this is that the $20 difference in price is 40% of the initial price of$50. Since this price difference results in a lower final price, give it a negative sign.

## Calculating Percent Decrease in an Alternative Way • For instance, say you’re trying to figure out how much a school’s enrollment changed between years. If the enrollment for this year is 12,125 and it was 13,500 last year, take 12,125 away from 13,500, which is 1,375. • In this case, divide 1,375 (the difference between the numbers) by 13,500 (the original value), which is equal to 0.1019 (when rounded). • Multiply 00.1019 by 100, which is 10.19. So, enrollment decreased by 10.19%.

Tip: If you use this equation and end up with a negative number, it represents a percent increase.

Next, subtract the old value from the new value. Then, divide the answer by the old value. Finally, multiply that number by 100 to get the percent change. For example, if the original value of something was 30 and then went up to 50, you would subtract 30 from 50 to get 20. Then, you would divide 20 by 30 and get 0.033. Finally, multiply that by 100 to get a final answer of 33 percent. For tips on how to find the percent change when there are more than two values, read on. Did this summary help you? Yes No

This can be anything from prices to time itself. And, it can represent a negative or positive change. As would be expected, positive values will indicate a percentage increase (e.g., a price raise), whereas negative values indicate a percentage decrease (e.g., a price cut). Percentage change is extremely useful in the world of finance , as one of the most important things it can represent is security . Security represents any kind of tradable financial asset. Forms of security include debt securities, equity securities, and derivatives. In the case of percentage change, you can track the price of security. You can use the percentage change formula to track individual securities, the value of currencies, and more. Used more simply, percentage change can also tell you how much the price of a product has increased or how much extra pizza you bought. Overall, it’s an incredibly useful concept for companies and individuals alike! Luckily, the formula for calculating percentage change isn’t very complex. First, find the difference between the two values you want to compare. Next, you divide the increase or decrease by the first initial value. Then, after multiplying that by 100 to get a percentage, you’re all set. Here’s the formula for percentage increase: Percentage change = (FV − IV) ÷ IV × 100 FV = final value IV = initial value Here’s the formula for percentage decrease: Percentage change = (IV − FV) ÷ IV × 100 FV = final value IV = initial value To better understand how to go about calculating percentage change, try following these step-by-step guides: ## Percentage increase First, as mentioned, calculate the difference between the initial value and the final value. This will allow you to find how much it’s increased. (increase = final value − initial value) Next, divide the increase by the initial value. This will give you a decimal. (decimal = increase ÷ initial value) Multiply the decimal you receive by 100 to get a percentage. (% increase = decimal × 100) This calculation is meant to represent a percentage increase, but if the percentage you get is negative, that would mean that the percentage change is a decrease. ## Percentage decrease First, calculate the difference between the initial value and the final value, but in reverse from the previous steps. This will allow you to find how much it’s decreased. (decrease = initial value − final value) Next, divide the increase by the initial value. This will give you a decimal. (decimal = decrease ÷ initial value) This calculation is meant to represent a percentage decrease, but if the percentage you get is negative, that would mean that the percentage change is an increase. In this first example, consider the following: James wanted to buy a$22 bowl set but didn’t have money at the time. When he returns to buy the same set, the price has increased to $26. James wants to know just how much the price has increased, as he doesn’t want to buy it if it’s increased by more than 20%. We can use percentage change to find just that. In this case, we’re looking for a percentage increase. First, calculate the difference between$22 (the initial value) and $26 (the final value). This will allow you to find out how much the price has increased. ($26 − $22 =$4) Next, divide the $4 by the$22. This will give you a decimal. ($4 ÷$22 = 0.18) Multiply the 0.18 by 100 to get a percentage. (0.18 × 100 = 18%) In this case, James will still buy the bowls because their price increase didn’t exceed 20%.

In this next example, we’ll examine how to calculate the percentage change of time as a resource.

Paul is working on a new product for his small business and wants to understand better how he should price it. To do this, he’s going to find the percentage change between how long it took him to make an old, similar product vs. this new product. Therefore, he can increase the price by the percentage change he calculates. The old product took 5 hours to make, whereas the new product takes 7 hours to make. How much is he going to increase the price? In this case, we’re looking for the percentage increase. First, calculate the difference between 5 hours (the initial value) and 7 hours (the final value). This will allow you to find out how much the price has increased. (7 − 5 = 2) Next, divide the two by the 5. This will give you a decimal. (2 ÷ 5 = 0.40) Multiply the 0.40 by 100 to get a percentage. (0.40 × 100 = 40%) In this case, Paul should increase the price of his new product by 40%.

In this example, let’s use the real-life values of the U.S. dollar to show how its value has inflated over time.

The currency of the United States has experienced inflation over a long period. This has decreased its value. $100 in 2010 is equal to$124.60 today. How much has the value of the dollar inflated in the past ten years? First, calculate the difference between $100 (the initial value) and$124.60 (the final value). This will allow you to find how much the value of the dollar has decreased. ($124.60 −$100 = $24.60) Next, divide the$24.60 by the $100, this will give you a decimal. ($24.60 ÷ $100 = 0.246) Multiply the 0.246 by 100 to get a percentage. (0.246 × 100 = 24.6%) In this case, the calculation was rather easy, but it shows that the value of the U.S. has been inflated by 24.6%. In this final example, we’ll calculate the percentage change of your net income over a five-year period. Five years ago, you earned a net income of$56,000. This year, you earned a net income of $73,000. If you’re curious about the percentage change of your net income across this five year period, here are the steps to follow: First, calculate the difference between$73,000 (the final value) and $56,000 (the initial value). This will show you how much your net income has increased. ($56,000 − $73,000 =$17,000) Next, divide $17,000 (the increase) by$56,000 (the initial value). This will give you a decimal. ($17,000 ÷$56,000 = 0.30) Multiply the 0.30 by 100 to get a percentage. (0.30 × 100 = 30%) Your net income has increased by 30% in the last five years.

As shown, percentage change is a great tool for calculating the value of time, products, currency, and more. It’s easy to calculate and can be useful for companies and individuals alike.

With that in mind, it’s worth noting that there are tons of ways percentages can be useful in financial situations. Here are some of the most common and useful ways percentages are employed:

Growth Rate

Inflation Rate

Marginal Utility

Variable Cost

And more! As you can see, there are a plethora of ways you can use percentages to your advantage. Exciting, right?

How do I calculate the percentage change between two numbers?

You calculate the percentage change between two numbers by finding the difference between the two numbers, dividing that number by the initial value, and multiplying the result by 100.

If you’re trying to calculate the percentage change between 360 and 700, you’d first find the difference (700 – 360 = 340). Then you’d divide 340 by 360 (the initial value), which is 0.94. Finally, to turn that into a percentage, you’d multiply it by 100, which gives you 94%.

What is the percent change when 25 is increased to 45?

The percent change when 25 is increased to 45 is 80%. To calculate this, you first find the difference between 45 and 25 — this gives you 20. Then, you take 20 and divide by the initial value, 25. This gives you 0.8. Finally, multiply 0.8 by 100 to find a percentage: 80%.

They all either require me to register my business (I’m not a business owner), or don’t work, or don’t load properly. I’m just baffled that their can this many idiots in Silicon Valley. Just how hard can it be to make an app that perform a simple function.

## Developer Response ,

Hi there, thanks for trying my app! I‘m just wondering what exactly did not work for you in this case? Could you send me a quick email to stuliapps@gmail.com to explain the issue? Greetings from Switzerland, ^as

## Great app!!!

Being a young adult with learning disabilities and not being able to have teachers who can help me with tasks like math (my weakness) has been a great help when I’m going out with my friends. I have trouble counting and making change. But with this app I feel so much better! Thank you so much to the developers of this app! <3 :)

## Great app !

I love the app, very clean and simple to use, i love the fact that there’s buttons so you don’t have to type each number every time (all though it would be nice to have for large numbers)

Forget clumsy formulas and standard calculators, our percentage change calculator does all the work for you. Just input the required information and you can determine the amount of change, as a percent that happened.

## Uses for Percentage Change

People use percentage change for a variety of reasons. Some of these may be:

• Percentage of weight lost on a diet
• Comparing crowd numbers for an event from day to day
• Percentage gained or lost in an investment
• Comparing sports statistics

The amount of change between two numbers is the difference, but just a difference does not mean much to many people. It has more of an impact when you say, “There was a 50 percent increase in attendance at the concert compared to last year,” versus when you say, “There were 100 more people at the concert this year than last.”

## How Percentage Change is Calculated

Our percentage change calculator uses the following formula to make the calculation:

((Ending Value – Original Value)/Original Value) x 100

## Information Our Calculator Uses

You do not need to remember this formula. You only need to input the following data into the calculator:

• Original value
• Ending value

The original value is the first number or the earliest number. For instance, if you are comparing concert attendance between this year and last year, the original value is last year’s attendance number.

The ending value is the most recent data. For the concert example, it would be the number of people who came to the concert this year. Just put these two numbers into the calculator to find the amount of change, as a percent.

## Money and Percentage Change

Money is another area where percentage change is frequently used. You can determine price changes as a percent or how much of a percentage change your salary raise gave you in your income.

• Mr. John started working as a software developer with a salary of $7000 and after a year salary is increased to$9000. Can you figure out how many percent of salary increment Mr. John got?
• The stock rate of a company collapsed from $67.93 to$58.91 within a few weeks. Find out the decrement of the rate in percentage.

Problems like these can easily be solved using our Percentage Change Calculator. Also, in this article, we will see how you can do it. In addition, we will learn about the mathematical approach behind the calculation. This amazing tool will help you to determine the change between two values in the terms of percentage. You just need to provide the starting and final value. After that, it will use its algorithm to calculate the result. In addition, it gives you the difference between two given values with calculation steps.

Calculating percentage change is a common task in the field of research, science, mathematics, technology, finance, statistics, and even in daily applications. So, it's a very useful tool for all types of users. There are some more financial calculators that you should try such as VAT Calculator UK and Australian GST Calculator .

## What is Percentage Change?

In layman's terms, it is the percent increase or decrease measured between two values. For example, if the final value increases X% from the starting value, we can say there is an X% change. Similarly, if the final value decreases Y% from the initial value, we can say there is a -Y% change. The positive change denotes an increase and the negative change denotes a decrease.

## Percentage Change Formula

To find the percentage change, firstly, find the difference between the final and starting value and then divide it by the mod of starting value. After that multiply the so obtained figure by 100 to get the percentage change.

The mathematical formula for calculating percentage change is as follows:

Where, X 1 = Starting value X 2 = Final value

The percentage change calculator yields result using the above formula.

## How to Calculate Percentage Change?

Let's take some examples where we will try to demonstrate the usage of the percentage change formula discussed and calculate the percentage change.

However, the online percentage change calculator is the most accurate and fast way to calculate the percentage change. But here we will know how the mathematical calculation works behind it.

In a company, the freshers are getting paid $9500 and after their training period gets over they will get$12000. Calculate the percentage change in their salary.

Here, Starting salary (X 1 ) = $9500 Final salary (X 2 ) =$12000

Now, place the above values in the percentage change formula.

Therefore, there is an approximate 26% increment in the salary after training.

A product costs $45 and you have claimed a flat discount of$10. Calculate how much percent you saved?

Here, Starting price (X 1 ) = $45 Final price (X 2 ) =$45 - $10 =$35

Therefore, there is an approximate 22% decrease in the price. Hence, you saved 22% from the original price.

## 1. Are percentage difference and percentage change the same?

No, percentage difference and percentage change are two different concepts. The percentage difference is calculated by calculating the difference between two averages. Whereas Percentage change is mainly the increment or decrement between two numbers in terms of percent(%).

## 2. How do you calculate 20% change?

Firstly, we need to have an initial value in order to calculate the change. Then we can tweak the percentage change formula to calculate the final value after 20% change.

Now let's take an example to understand in detail.

Suppose we have, Starting value = 100 and, Percentage change = 20%.

Let's put the known values into the equation.

X 2 = 20 + 100

Therefore, X 2 = 120

Also, you can use the following formula to directly calculate the final value. Just place the starting value in the equation and find out the final value.

## 3. How to calculate percentage decrease?

Whether you want to calculate percentage increase or decrease the process remains the same.

Put the initial value and final value into the formula and solve it. Remember that, the percentage change will come in negative. For more understanding refer to the second example in the how to calculate section.

In our calculator just enter the values in the correct order and press the "Calculate" button. When computing for decrease, the Starting value will be greater than the Final Value.

## 4. What is the limit of input values?

There is no limit on the input values. You can input any big or small value as you want.

## IRS announces new tax brackets for 2024. What does that mean for you? The Internal Revenue Service has announced that income tax brackets and standard deductions will be changing come the 2024-2025 season.

The IRS released the information Thursday in its annual inflation adjustments report, revealing a 5.4% bump in income thresholds to reach each new bracket.

The IRS makes these changes annually, using a formula based around the consumer price index to address inflation and prevent "bracket creep," which happens when inflation pushes taxpayers into a higher bracket without any real increase in income or buying power.

While this bump is lower than last year's historical 7% increase , it is still more significant than times in the past when inflation was lower than the current 3.7%.

There are seven federal income tax rates as set by the 2017 Tax Cuts and Job Act and they are applied progressively, meaning the more you earn, the higher percentage of taxes you pay from your income. The rates currently are set at 10%, 12%, 22%, 24%, 32%, 35% and 37%.

For 2024, the lowest rate of 10% will apply to individual with taxable income up to $11,600 and joint filers up to$23,200. The top rate of 37% will apply to individuals making above $609,350 and married couples filing jointly earning$731,200 or more.
